DISPENSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 774,888, dated November 15, 1904.

Application filed April 29, 1904. Serial No. 205,580. (No model.) I

T0 all whom it may concern:

Be it known that I, EDWARD E. MURPHY, a citizen of the United States, residing in Chelsea, county of Suffolk, and State of Massachusetts, have invented an Improvement in Dispensing Apparatus, of which ,the following description, in connection withthe accompanying drawing, is a specification, like letters on the drawing representing like parts.

The present invention relates to a dispensing apparatus for syrups to be used in connection with soda-fountains, and is embodied in a device to be used in connection with a syrup-jar so constructed as to deliver a measured quantity of syrup at each operation.

In the construction shown the syrup-jar is in the shape of a tank arranged to be slid into a chamber and provided with a pocket or recess at the bottom, from which the syrup is delivered to the nozzle. In conjunction with the delivery-nozzle a plunger is utilized and arranged to be forced into the said recess, the said plunger having openings which communicate with the delivery-passage, so that as the plunger is forced intothe recess a certain definite amount of syrup is forced upward through the delivery-,passage and out of the delivery-nozzle. The plunger and deliverypassage are arranged to be supported above the jar and may be removed when the jar is to be removed for relling or cleaning. The delivery tube and nozzle are preferably formed in one piece and provided with an annular flange resting 'on a support or shoulder above the receptacle which contains the jar, the delivery-tube constituting a guide for the plunger, which is depressible with relation thereto by means of a suitable actuating knob or handle.

The drawing is a view, partly in section and partly in side elevation, of a dispensing apparatus embodying the invention.

The syrup is contained in a jar or tank a, which is arranged to be slid into a chamber or receptacleA, having a door or cover A2 at the front, the soda-fountain being commonly provided with a number of said chambers, each of which is adapted to contain a jar of syrup.

As herein shown, the jar a is provided with flanges a2, which fit over supporting members A3 near the top of the chamber, each jar being slid into one of the chambers like a drawer. In the drawing one only of the Iianges a2 is shown, the other'being at the opposite side of the jar.

In order to'deliver the syrup from the jar in measured quantities, the said jar is provided with a pocket or recess a3, from which the syrup isarranged to be forcedv by means of a plunger b, which normally stands above the said pocket, but is arranged to .be forced downward into the said pocket, in which it lits closely,the syrup being forced out of the pocket through passages b2, formed in the plunger. These passages communicate with the dispensing-tube c, which is provided with the outlet-nozzle c2, so that the syrup forced out of the pocket c3 is discharged from the said nozzle, substantially the same amount of syrup being discharged at each depression of the plunger. The dispensing-tube c is arranged to constitute a guide and support for the plunger which is shown as having a sleeve b3 surrounding the tube c and an operating-rod L" within the tube, the said ro'd projecting' through a passage c3 near the top of the part in which the dispensing-tube c and the outletnozzle c2 are formed. The passage c3 constitutes a guide for the top of the rod If, and in order to maintain the plunger b in its normal position a spring is interposed between the part in which the passage c3 is formed and a 'ringer-piece or actuator Z2, secured to the top of the rod b4. In order to inclose the said spring and to aord a supplemental guide for the rod b4, a sleeve 57 is fitted around the spring and the actuator member 6', the said sleeve being shown as threaded upon the part in which the dispensing-tube c and the nozzle c2 are formed. V

As herein shown, the tube c and nozzle c2 are formed in a single casting which is provided with an annular tongue 0*, which ts into an opening A4 at the top of the chamber A, this member and the plunger being supported by means of a iiange c5, which rests on the top ofthe chamber around the said opening.

The dispensing-tube, nozzle, and plunger can be removed at any time by simply lifting the whole thing out of the opening A", so that this part of the apparatus can be frequently cleaned withouttrouble. The removal of this part, moreover, leaves the jar a free to be withdrawn from the chamber A to be cleaned or refilled.

Then the device is in use, a definite amount of syrup is obtained by pressing downward upon the actuating-knob b, which knob and plunger at once return to normal position, owing to the action of the spring.

What I claim isl. In a dispensing apparatus for syrups, the combination with a jar provided with a pocket or recess; of a casing for said jar, a dispensingtube suspended from said casing over the said recess; a plunger supported by said dispensing-tube, said plunger substantially fitting the Said recess; means for forcing said plunger downward with relation to said tube in the said recess; and openings throughj said plun ger communicating with said recess, substantially as described.

2. In a dispensing apparatus, the combination with a dispensing-tube; of a plunger movable with relation to said tube and guided and supported thereby at each end; a spring acting on said plunger to hold the same in a definite position with relation to said tube; openings through said plunger communicating with said tube; and a receptacle for syrup, substantially the same in peripheral size and shape as that of the plunger, and in alinement with said plunger, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD E. MURPHY.
